Why Are MIDI Files So Small?

MIDI files are small because they contain instructions rather than actual audio data. Unlike audio files, which store detailed sound wave information, MIDI files store a series of commands that tell a synthesizer or computer how to generate sounds. Here’s a closer look at why MIDI files are so compact:

1. Data Type

  • MIDI Files Contain Instructions: MIDI stands for Musical Instrument Digital Interface. MIDI files contain instructions like which notes to play, how long to play them, how loud they should be, and which instrument should be used. These instructions are encoded as simple, compact data.
  • No Audio Data: MIDI files do not store audio waveforms. Instead, they store numerical representations of musical events (e.g., “play note C4 with a velocity of 90”). This is fundamentally different from audio files, which store the actual sound waves as large sets of data points.

2. Efficiency

  • Event-Based System: MIDI is an event-based system where each event (such as a note being played or a control change) is represented by a few bytes of data. For example, a “Note On” message requires only 3 bytes: one for the command itself (which note), and two for the note and velocity.
  • Minimal Data Required: Because each MIDI event requires so little data, even a complex piece of music with multiple instruments and extensive control changes can be represented with just a few kilobytes.

3. Channel and Track Organization

  • Use of MIDI Channels: MIDI files organize data into channels, where each channel can control a different instrument. Multiple channels can be managed within a single track, and all this information is packed efficiently into the file.
  • Track Information: In MIDI Type 1 files, the data is organized into multiple tracks, but these tracks only contain the essential commands, which take up minimal space.

4. Absence of Audio Recording

  • No Sound Recording: MIDI files do not record or store sound. They do not capture audio from a microphone or any other source. This dramatically reduces the file size compared to audio files like WAV or MP3, which store detailed information about the sound waves.

5. Repeatable Instructions

  • Repetitive Commands: Many MIDI sequences involve repeated instructions, such as the same note or control change being triggered multiple times. MIDI efficiently encodes these repetitive elements without requiring additional storage for each instance.

6. Text-Based Information

  • Inclusion of Lyrics or Meta-Events: Even when MIDI files include lyrics or other meta-events (like tempo changes), this data is still text-based and occupies very little space compared to the audio data.

Example of File Size Differences:

  • MIDI File: A typical MIDI file for a song might be as small as 5–50 KB.
  • Audio File: An equivalent audio file (e.g., WAV or MP3) of the same song could range from 5–50 MB, depending on the format and quality.

Summary:

MIDI files are small because they don’t store actual audio but rather the instructions needed to generate the audio. This event-based system, combined with the efficient encoding of musical commands, makes MIDI files extremely compact. The small file size is one of the reasons why MIDI is still widely used in music production, especially in scenarios where flexibility and ease of manipulation are important.

What MIDI Channel Should I Use?

Choosing the appropriate MIDI channels depends on your specific setup and the type of musical performance or production you’re working on. Here’s a breakdown of what MIDI channels are, how they work, and some general guidelines on which channels to use in different situations.

Understanding MIDI Channels

MIDI (Musical Instrument Digital Interface) uses channels to manage different instruments or parts in a composition. A single MIDI connection can carry up to 16 channels, each capable of transmitting a separate stream of MIDI data. This allows multiple instruments or parts to be controlled independently within the same MIDI system.

Common MIDI Channel Assignments

  1. Channel 1: This is typically the default channel for most MIDI controllers and instruments. If you’re controlling a single instrument, it’s common to use Channel 1.
  2. Channel 10: Reserved for percussion/drums in the General MIDI (GM) standard. Drum machines, drum kits, and other percussive instruments are often assigned to Channel 10.
  3. Channels 2-9, 11-16: These channels are usually available for other instruments or parts in your composition. You can assign different instruments or voices to each of these channels.

When to Use Specific MIDI Channels

  • Single Instrument Setup: If you’re controlling only one instrument, you can simply use Channel 1. In this case, there’s no need to worry about channel assignments unless you introduce more instruments or parts.
  • Multiple Instruments: When working with multiple instruments, assign each one to a different MIDI channel. For example:
  • Channel 1: Piano
  • Channel 2: Bass
  • Channel 3: Strings
  • Channel 4: Synth Lead
  • Channel 10: Drums (as per GM standard)
  • Percussion/Drums: Always use Channel 10 for drums if you’re following the General MIDI standard. Most MIDI drum kits and percussion instruments are designed to default to Channel 10.
  • Layering Sounds: If you want to layer multiple sounds to play simultaneously from the same MIDI input, you can assign the same MIDI channel to different instruments. For instance, assigning both a piano and a string sound to Channel 1 will allow you to trigger both sounds together.
  • Split Keyboard: Some keyboards allow you to split the keyboard so that different sections control different instruments. For example, you could assign the lower keys to Channel 2 (bass) and the upper keys to Channel 1 (piano).

Practical Tips for MIDI Channel Usage

  • Organize Your Channels: When working on complex projects with multiple instruments, it helps to organize your channels logically. For example, use Channels 1-4 for melodic instruments, 5-8 for harmonics or pads, and 10 for drums.
  • Avoid Overlap: Make sure that different instruments that are supposed to be independent are assigned to different channels. Overlapping channels can lead to unintended sounds or control issues.
  • DAW and Synthesizer Defaults: Some DAWs or synthesizers may have default channel settings. Be aware of these defaults, especially when connecting multiple devices, to avoid conflicts.
  • MIDI Channel Filtering: Some advanced MIDI setups allow you to filter or remap MIDI channels. This can be useful in complex live performance setups where you need to route specific data to particular instruments.

When to Use Specific Channels

  • Simple Home Studio Setup: For a basic setup with a few instruments, using Channels 1-5 for your main instruments and Channel 10 for drums is usually sufficient.
  • Live Performance: In a live setup with multiple MIDI devices, carefully assign each device to a unique channel to ensure that each instrument responds correctly to your performance.
  • Orchestration: For orchestral compositions or complex arrangements, use a systematic approach to channel assignment, reserving specific channels for different instrument families (e.g., strings, brass, woodwinds).

Conclusion

The choice of MIDI channels is all about organizing your MIDI data efficiently and ensuring that each instrument or part of your composition responds as intended. For most setups, using Channel 1 for your primary instrument and Channel 10 for drums is a good starting point. As you add more instruments or complexity to your setup, assigning each one to its own channel will help keep your MIDI data organized and easy to manage. Whether you’re working in a home studio, performing live, or composing an orchestral piece, thoughtful MIDI channel assignment is key to a smooth and successful musical workflow.

1. MIDI Lyric Meta Events

MIDI files can store lyrics using Lyric Meta Events. These events are a part of the MIDI standard and are specifically designed to embed text, such as lyrics, into a MIDI sequence. Each word or syllable of the lyrics is associated with a specific time in the track, allowing them to be displayed in sync with the music.

  • Meta Event Type: The MIDI event type used to store lyrics is the Lyric Meta Event (0x05).
  • Text Data: The actual lyrics are stored as text data within these events.

2. Software for Adding Lyrics

To add lyrics to a MIDI file, you typically use a MIDI sequencing or editing software that supports Lyric Meta Events. Here’s how you can do it:

Using Digital Audio Workstations (DAWs)

Some DAWs and MIDI editing software allow you to add lyrics directly to a MIDI track. Examples include:

  • Cakewalk by BandLab: One of the most popular DAWs for handling MIDI lyrics. You can input lyrics directly into the MIDI track and align them with the corresponding notes.
  • Cubase: Another DAW that allows the addition of lyrics via the MIDI editor.
  • MuseScore: A free notation software that supports adding lyrics to MIDI files.

Steps to Add Lyrics in a DAW

  1. Import or Create a MIDI Track: Start by importing an existing MIDI file or creating a new MIDI sequence in your DAW.
  2. Access the MIDI Editor: Open the MIDI editor in your DAW to view the MIDI events. There should be an option to add or edit lyrics.
  3. Enter Lyrics:
  • In Cakewalk, for example, you would use the Lyric View to input lyrics, aligning each word or syllable with the corresponding note.
  • In MuseScore, you can select the note where the lyric should appear, and then type the word or syllable.
  1. Sync Lyrics with Music: Ensure the lyrics are synchronized with the music. Each word or syllable should be associated with the appropriate note, allowing it to display in time with the music during playback.
  2. Save the MIDI File: Once the lyrics are added and synced, save the MIDI file. The lyrics will now be embedded in the file as Lyric Meta Events.

3. Karaoke MIDI Files

MIDI files with embedded lyrics are often used in karaoke systems. These files are typically referred to as MIDI-Karaoke or KAR files (MIDI files with a .kar extension).

  • KAR Files: These are specialized MIDI files that include lyrics and other metadata designed for karaoke systems. Many karaoke software programs support these files and can display the lyrics on the screen in sync with the music.

4. Playback of MIDI Files with Lyrics

To view and play back the lyrics embedded in a MIDI file, you’ll need a compatible MIDI player or software that can interpret and display the Lyric Meta Events.

  • MIDI Players with Lyric Support: Some MIDI players, such as vanBasco’s Karaoke Player, can display lyrics as the MIDI file plays.
  • DAWs: Many DAWs that support MIDI lyrics can also display them during playback, allowing you to see how the lyrics align with the music.

5. Considerations

  • Encoding: Ensure that the lyrics are encoded in a supported character set, usually ASCII or UTF-8, to avoid issues with special characters.
  • Timing: Precise timing is crucial when syncing lyrics with music. Pay attention to the placement of each Lyric Meta Event to ensure they display correctly.

Conclusion

Lyrics can be added and stored in MIDI files using Lyric Meta Events, making it possible to synchronize text with music for applications like karaoke or live performance. By using MIDI editing software or DAWs that support lyric entry, you can embed the lyrics directly into the MIDI file, ensuring they play back in sync with the corresponding notes.

Chaining Multiple MIDI Instruments Together

Chaining multiple MIDI instruments together, often referred to as MIDI daisy-chaining, is a technique where multiple MIDI devices are connected in series. This allows a single MIDI controller (such as a keyboard) to send MIDI data to multiple instruments or sound modules. This setup is useful in various scenarios, from live performances to complex studio setups.

How to Chain Multiple MIDI Instruments Together

To chain multiple MIDI instruments together, you will typically use the MIDI Thru port on your devices. Here’s a step-by-step guide on how to do it:

1. Start with the MIDI Controller

  • MIDI Out: The first device in the chain is usually your MIDI controller, such as a keyboard or DAW. Connect a MIDI cable from the MIDI Out port of the controller to the MIDI In port of the first instrument in the chain.

2. Connect the First Instrument

  • MIDI Thru: After connecting the first instrument’s MIDI In port, use another MIDI cable to connect the MIDI Thru port of the first instrument to the MIDI In port of the second instrument.

3. Add More Instruments

  • Repeat the process, connecting the MIDI Thru of one instrument to the MIDI In of the next, until all your instruments are connected.

4. MIDI Channel Assignment

  • Assign each instrument in the chain to a different MIDI channel. This allows the MIDI controller to send specific data to each instrument independently.

Example Setup

  1. MIDI Controller: Connect the MIDI Out to the first instrument.
  2. Instrument 1: Connect MIDI Thru to Instrument 2.
  3. Instrument 2: Connect MIDI Thru to Instrument 3.
  4. Instrument 3: No further connections unless adding more instruments.

Why Chain Multiple MIDI Instruments?

Chaining MIDI instruments together offers several benefits, particularly in live performances and complex studio environments.

1. Expand Your Sound Palette

  • By chaining multiple instruments, you can significantly expand your sound palette. For example, you can have a synthesizer, drum machine, and sound module all responding to different MIDI channels from a single controller. This setup allows you to create richer, more complex soundscapes.

2. Simplify Control

  • MIDI daisy-chaining allows you to control multiple instruments from a single controller, such as a MIDI keyboard. This is especially useful in live performances where you might want to trigger different sounds or instruments without switching controllers.

3. Layered Sounds

  • Chaining MIDI instruments allows you to layer sounds by assigning multiple instruments to the same MIDI channel. For example, you could have a piano, string ensemble, and synth pad all play the same notes simultaneously, creating a fuller, more textured sound.

4. Efficient Use of MIDI Ports

  • In setups with limited MIDI ports (such as on older devices or simpler interfaces), daisy-chaining can help maximize the number of instruments you can connect without requiring additional MIDI interfaces.

5. Complex Arrangements

  • In studio settings, chaining MIDI instruments is useful for creating complex arrangements where different parts of a composition are played by different instruments. This setup allows for more detailed and dynamic compositions.

Potential Challenges

While chaining MIDI instruments together can be highly beneficial, there are a few challenges to be aware of:

  • MIDI Thru Latency: Each device in the chain introduces a slight delay as the MIDI signal passes through. While typically negligible, this can become noticeable if many devices are chained together.
  • Limited MIDI Channels: With only 16 available MIDI channels, a large setup might require careful channel management to avoid conflicts.
  • Signal Degradation: Over long chains, especially with many devices, there might be slight signal degradation. Using MIDI signal boosters or splitters can help if this becomes an issue.

Alternatives to Daisy-Chaining

  • MIDI Splitters: For large or complex setups, using a MIDI splitter allows one MIDI Out signal to be sent directly to multiple MIDI In ports simultaneously, reducing latency and signal degradation.
  • MIDI Interfaces: In a studio environment, using a multi-port MIDI interface can help manage multiple devices more efficiently, providing direct connections from a DAW to each instrument.

Conclusion

Chaining multiple MIDI instruments together is a powerful way to expand your musical setup, allowing for more complex arrangements, layered sounds, and efficient control. Whether you’re performing live or working in a studio, understanding how to daisy-chain MIDI devices can greatly enhance your creative possibilities. While there are some challenges to consider, the benefits of a well-organized MIDI chain can be substantial, offering greater flexibility and control over your music production.

Do you sacrifice sound quality by going digital?

The debate between digital and analog music production is a longstanding one, with arguments on both sides regarding sound quality, convenience, and artistic expression. Whether producing digital music sacrifices sound quality compared to analog music depends on several factors, including the context, the listener’s preferences, and the quality of the equipment and processes used. Here’s a breakdown of the key considerations:

1. Sound Quality Differences

  • Analog Sound: Analog recording captures the continuous waveform of sound. Vinyl records and tape recordings are examples of analog formats. Proponents of analog argue that it provides a warmer, richer, and more natural sound, particularly because it captures subtle nuances and harmonics that some believe are lost in digital formats.
  • Digital Sound: Digital music is recorded and stored as binary data (1s and 0s). It involves converting the continuous analog signal into discrete digital data through a process called sampling. The quality of digital sound depends largely on the sample rate (how often the sound is measured) and bit depth (how much information is captured in each measurement). High-resolution digital formats can achieve very high sound quality, often indistinguishable from analog to the average listener.

2. Advantages of Digital Music Production

  • Precision and Flexibility: Digital music production allows for precise editing, manipulation, and processing of sound. Producers can easily cut, copy, paste, and alter audio without degradation in quality, which is difficult with analog.
  • Portability and Accessibility: Digital files are easy to store, share, and distribute. Digital audio can be streamed, downloaded, and played on a wide variety of devices, making music more accessible to listeners worldwide.
  • Consistency: Digital recordings do not degrade over time, unlike analog formats like tape, which can wear out or degrade with repeated playback.
  • Advanced Processing: Digital audio workstations (DAWs) and plugins offer powerful tools for sound design, mixing, and mastering, giving producers a vast array of creative options that are not possible with analog equipment.

3. Perceived Loss of Quality in Digital Music

  • Sampling Limitations: While modern digital recordings can capture audio at very high quality, there is still some loss of information during the analog-to-digital conversion process. For instance, when audio is sampled at 44.1 kHz (the standard for CDs), certain high-frequency details may be lost, though this is often imperceptible to most listeners.
  • Digital Artifacts: Poorly executed digital processing can introduce artifacts such as aliasing, quantization noise, or digital distortion, which can negatively impact sound quality. However, with high-quality equipment and careful processing, these issues can be minimized or eliminated.
  • Psychological Factors: Some listeners perceive digital music as “colder” or “less organic” compared to analog because of the way it is processed. This perception can be subjective and influenced by personal preference or familiarity with analog sound.

4. Hybrid Approaches

Many modern producers use a hybrid approach, combining the best of both analog and digital worlds. For example, a producer might record instruments using analog equipment to capture that warm, rich sound, and then use digital tools for editing, mixing, and mastering. This approach can provide the warmth of analog with the precision and convenience of digital.

5. Listener Experience

Ultimately, whether digital music production sacrifices sound quality is subjective and depends on the listener’s experience, preferences, and the listening environment. In many cases, high-quality digital music can sound virtually indistinguishable from analog, especially with advancements in digital recording and playback technology.

Conclusion

Producing digital music does not necessarily mean sacrificing sound quality. While there are inherent differences between analog and digital sound, each has its strengths. Digital music offers unparalleled flexibility, precision, and convenience, while analog can provide a unique warmth and character. The choice between analog and digital often comes down to the specific needs of the producer, the desired sound, and the preferences of the listener. Many modern music productions successfully combine both analog and digital elements to create the best possible sound.
